[Antennas] Recommendations Please

Put up a HORIZONTAL loop cut (ak: cloud warmer) for 80mtrs and use a
tuner on it...it will have the high angle of radiation you need for non
DX net work on 80 and will show gain on 40-above with the angle of
radiation coming down (because of its height vs wavelength at the band
in question)...If you want tuned or trapped, I really cannot recommend
anything off the top of my head (and it is past midnight as I type this!
:)

Ahhh btw feedline will not improve the antenna....feedline only improves
loss between the radio and antenna...but if the antenna is not working
right in the 1st place, different feedline will not make it better..(may
make it worse if it adds additional loss) At HF, coax vs ladder line is
not much different in loss factors under usual conditions..
